It is currently impossible to specify most of the buildProperties through the yaml.

Reproduction

*** Create an empty bom.yml and the following packager config:

bundle:
  title: "Demo Runner"
buildSettings:
  bom: "bom.yml"

• Run the cwp with this configuration and observe:

Exception in thread "main" java.io.IOException: Neither Jenkins core nor Jenkins war have been defined by configuration file or BOM/POM

Workaround

Pass the properties (eg BOM) in the cli arguments
